Abstract

The present invention relates to a transparent thick copolyester sheet having a light transmittance of at least 82% and a haze of at most 5%, the copolyester being composed of
  • (A) an acid component comprising
  • (i) a terephthalate moiety as major component,
  • (ii) a 2,6-naphthalene dicarboxylate moiety,
    and
  • (iii) optionally, an isophthalate moiety,
    • and
  • (B) a glycol component comprising
  • (i) ethylene glycol, and
  • (ii) optionally, 1,4-cyclohexane dimethanol.
    • A transparent thick copolyester sheet of the present invention is suitable for various industrial usages such as glass substitute of automobile, window glass substitute of high building, and transparent soundproof wall.
